To all whom it may concern:

Be it known that l, llENni llENnEiisoN, a citizen oi the United States, residing in the borough ot Manhattan, city, county, and

State of New York, have invented a certain j lin roved Mold ltannning Apparatus, of

which the following is a specification.

rl`his invention 'relates to apparatus lorrainining molds for cylindrical castings such as pipe. The driven and are so mounted as to be adjustable vertically and horizontally, and are-carried by a support that swivels about a vertical axis, being 'suspended flexibly therefrom out oi line with said axis. The apparatus inay be used with statioiiary or rotatable molds. By the vertical and horizontal adjustments the rainn ers may be`readily adjusted to molds of dillerent diameter and arrange` ment. The swiveling support permits the pendent raini'ners to be brought into propel' relation to the inoldnas, for instance, if the axis oi' the support coincides with thel axis ofthe inold the radius of the points of suspension of the raininers may be substantially the radius of the i'nold. This construction perinits of the employment of a plurality of raininers suspended from a single support.

ln the accompanying drawings which show one form in which this invention may be embodied: Figure l is a general elevation partly in, section and partly broken away ior convenience ot' illustration upon one sheet: Fig. 2, a vertical section through a flexibly supported swiveling raininer cylinder support: and Fig. 3, a detail sectional view showing the end of a raininer cylinder, the rannner shaft and bit and a guide sleeve or tube surrounding the shaft and. attached to the lower head of the cylinder.

A column is properly supported upon a suitable liormdation, to be detachable there- Vtrom for transportation il desired. composed of a portion u. and a rotatable upper portion turning upon balls c running in an annular race-way between the two The upper end of the part l carries a horizontal l'rame provided with tracks or ways upon which runs n i ias-e oi the cjf'hndriral body /f luis torined in` a small truck c to which lis connected a rope l["passingovei an idler on a bracket at the end ol' the horizontal lramc and thence back over another idler pulley adjacent the column from whence it entendsdownwardly, its lower end being provided, desired, with a rannners are pomir;E

lt is i chain and equipped with a suitable ring f l adapted to be engaged with a projection or j catch g on the side of the column.

li is a pipe extending up along the side of the column and adapted to be connected at its bottoni with a source of Huid under pressure. At It it is provided with a suitable hand controlling-valve and at the top its turned over end is coupled to a length of Vllexible armored hose t which passes under a pulley to which is attached a counter weight i., thence np overa pulley t2 at one end ofthe horizontal frame l), thence over a grooved wheel lorining part of the movable truck c and thence downwardly, its end being connected to a swiveling raniiner su constructed as presently described. The t parts are so counter-weighted that there is j 'a slight tendency of the truck e to run ini wardly and it may be drawn outwardly or away i'roin the axis of the column and secured in position by the rope or cable j'.

The rammel' supporting apparatus, indicated generally by the letter J in Fig. l, inay be composed of a horizontall divided casting j, the sections of w hich are held toffetherby bolts. The upper section has a tu ular extension y tapped at its upper end and formed with a lateral extension je tapped at its outer end and shown in Fig. 2 as closed by a screw plug. The lower section has a tubular extension j", the axis of which is coincident with that of the tubular extension j. In a cylindrical chamber between the two sections j, j of the casting and supported upon anti-friction balls j* is a ilat cylindrical body lc having froin`its under face a tubular extension It" extending into the enlarged lower end of the 'part j. This tubular extension corinects with another tubular extension f; eX- tending from the bottoni of /r 'through the tubular extension ji* on the lower section of the casting'. 'the lower end o1 lr is tapped to receive the threaded end ol' one branch of a T-coupling 1n., the other ends ol which are tapped. A llexihle ring valve n is applied to the upper end ol` lc in suf-h way as to seal the joint between it and thel part j when a compressed llnid is introdueml. 'l he upper it an annular channel for the reception of a packing ring ln which runs in contact with the under face of the upper section of the. 3 im'losingeasting. Onebranchol' tlieT-coup- I ling 1n has screwed into it a rod or length of j f2, i 876,054

surrounding it he tube is preferably em ployed in all cases. 'l he drawing showsla pipe mold mounted upon a revolving platformr rotation of which is produced by any,

suitable power as a motor o, driving a pinion Z running in a rack on the rotating platform v. This invention is. shown embodied' in.. a form deemed to be practicable and eiiicient but obviously it may beembodied in other organizations without departing from the 75 principles of construction andrmode of operation herein disclosed.
